Ultrasonic investigations of aqueus solutions of a-cyclodextrin and amphiphylic substances having different "heads" and identic "tails"

Velocity and absorption of ultrasonic waves in aqueuos
solutions of a-cyclodextrin containing amphiphil substances with different
``heads" and identic ``tails" were carried out. As a result of the mutual
interactions between a-cyclodextrin and the amphiphil substance the low
frequency ultrasonic relaxation process has been established. Thermodynamic and
kinetic parameters related to this process have been calculated. Obtained
results have been discussed considering molecular structure of the amphiphil
substances.
